An outbreak of the cyclospora parasite has spread to nine US states, making it one of the largest reported cases in recent history. The illness is tied to iceberg lettuce from central Mexico, and health officials have linked it to cases in Illinois, Kansas, Oklahoma, and Pennsylvania. Additional states including Indiana, Kentucky, Michigan, Ohio, and West Virginia have also reported illnesses connected to the same lettuce source.
The parasite causes a condition known as cyclosporiasis, which leads to severe diarrhea and other gastrointestinal symptoms. There are multiple outbreaks in the country, each likely from a different source, complicating efforts to track the illness. Since mid-May, the number of reported cases has risen to more than 11,000 across 41 states. Michigan has been the hardest hit, with over 8,100 people infected according to local health officials.
People who have fallen ill described the experience as extremely painful and difficult to endure. Taylor Farms, a major supplier of fresh vegetables in the United States, recalled all its iceberg lettuce from central Mexico on July 17. The company acted out of caution, even though the source of the outbreak was not yet confirmed.
Federal investigators initially said that lettuce from Taylor Farms tested positive for cyclospora, but later retracted that statement. The Food and Drug Administration later confirmed the result was a false positive, which added to confusion among the public.
One major challenge in identifying the source is that symptoms can appear weeks after consuming contaminated food. Experts say this makes it hard to trace what someone ate and connect illnesses to a common source.
The investigation into the outbreak is expected to take a long time, according to food safety experts. People across the country have changed their eating habits due to the outbreak, avoiding salads and even questioning whether it’s safe to eat burrito bowls. Confusion has grown as officials have issued conflicting messages about what foods are safe.
The situation has led to a lack of trust in public health guidance, especially when information changes quickly. Taylor Farms’ recall came after federal officials linked it to the outbreak, but the company’s lettuce was later found to be a false positive. Taco Bell, a major fast-food chain, was affected by the recall and removed all lettuce from Taylor Farms from its menu nationwide.
At least 1,644 people reported eating at Taco Bell before becoming ill. The false positive result from the FDA caused confusion and concern among consumers and businesses alike. Experts explained that false positives can happen in food testing, but they still damage public trust.
Social media has amplified the spread of misinformation, making it harder for companies to correct the record. Businesses are trying to distance themselves from the outbreak, but many efforts have not been effective in restoring consumer confidence. Even independent restaurants have felt the impact, with some seeing a sharp drop in customers after the outbreak was reported.
Some restaurant owners say they are struggling to keep their businesses afloat due to the decline in foot traffic. Experts suggest that clear and consistent communication is key during a food safety crisis. They pointed to McDonald’s response during a similar outbreak in 2024 as an example of how to handle such situations. McDonald’s took clear actions and communicated them effectively, which helped maintain public trust during the event.
However, experts note that managing a crisis like this is difficult and requires strong leadership.

Located near his the greenhouses are two circular crops of long-leaf pines seedlings under a pivot irrigation system equipped with micro-sprinklers. Long-leaf pines are an indigenous tree in the Southeast. Growers are working to increase the number of this slower growing hearty hardwood tree in this region.
The farm’s operation includes bell peppers, cucumbers, eggplant, squash, strawberries, tomatoes, cantaloupe, watermelon and a variety of specialty peppers on 6,500 acres; and cotton and peanuts on 1,000 acres.
Mr. Brim talks about the immigration and disaster relief challenges following Hurricane Michael. USDA helped this farm with the Farm Service Agency (FSA) Emergency Conservation Program (ECP) for structural damage cleanup. He also mentions the importance of having Secretary Sonny Perdue, a person with agricultural background, come visit and listen to 75 producers six months ago, in southwest Georgia.
